The screw 12 extends through the apertured ears 90 and a knurledadjusting nut 92 is mounted on the screw intermediate the ears 90.

The purpose of the nut 92 will also be later explained.

'Ihe projections 34 and 36 are formed on their inner sides withdovetailed recesses 94 and 96 and the projections 34 and 36 are providedwith openings 98 and |00 which lie at right angles to the recesses 94and 96.

The dovetailed recesses 94 and 96 formed in the extension bars permitthese bars to be added to the frame as desired.

The openings 98 and |00 are to receive the marking tool |02 or similargauges having stems which will fit the openings 98 and I 00.

The opening 16 in the gauge portion 48 is used in a similar manner withmarking tool |04.

Gauge markings |06 are provided on the bar 22, which start from a pointone-half inch from the center of the opening 98 and extendlongitudinally of the bar 22 to the right of the opening 98.

These markings start at 5 and progress to 0 or the one inch point indivisions of ten between each inch, and from the one inch point theyprogress to the eight inch mark. The space between each inch mark isdivided into equal spaces as previously stated and each of these spacesis divided into four equal spaces representing twenty-live onethousandths of an inch.

On the gauge portion 48 the markings |68 will coact with the gaugemarkings |06 on the bar 22 in a similar manner as the gauge Vernier of aheight gauge.

This arrangement and coaction of the gauge markings permits readings inthousandths of an inch between points. The bars may be changed as toshape and size depending upon the requirements of the job to be done,and as stated bars of any length can be inserted in the dovetailedrecesses 94 and 96 of the projections 34 and 36 to extend the length ofthe measuring instrument or connection may be made by other methods.

. In operation the marking tool |02 is placed in the constructionopening and the rider bar 18 is slid on the frame to a pointapproximately close to the position of a hole to be bored. The set screw86 is tightened rmly fixing the bar 18 to the frame 2|] then the nut 92is turned sliding the gauge portion 48 forward or backward until theexact center of the hole to be bored is determined, then the markingtool |02 will be given a slight blow to mark the center of the new holeafter the screw 68 has been tightened to x the portion 48 in position.This operation is repeated until the centers of all the holes to bedrilled have been determined;

Since the small scale markings |08 are divided into twenty-ve spacesconstituting twenty-four spaces on the large scale markings |06, thereadings can be made in thousandths of an inch.

From the foregoing it will be seen that a very simple and compact formof measuring instrument has been provided, which is constructed to ahigh degree of accuracy for emciently performing the objects of theinvention.

The instrument in its entirety is made of light and durable metal, andit is to be understood that the structural details and combinations ofthe various parts are susceptible to variations and modifications asfall within the spirit of the invention and the scope of the appendedclaims.

Having thus described the invention what is claimed as new and desiredto be secured by Letter Patent is:

1. In a measuring instrument having a frame provided with a plurality ofrelatively spaced longitudinally extending bars bridged at one end by ablock and at their other end by a web to form outwardly extendingparallel projections the improvement comprising, an elongated slidinggauge member mounted between two of said longitudinally extending bars,coacting guide means on said bars and said gauge members to retain' saidgauge member between said bars, gauge markings on one of said bars andgauge markings on said gauge member adapted to coact with the gaugemarkings on said bars, a foot portion on said gauge member extendingfrom said gauge member in a plane perpendicular to the longitudinal axisof said gauge member, a toe portion extending from said foot portion ina plane perpendicular to the longitudinal axis of said foot portion andon said foot portion forming a recess between said toe portion and saidgauge member, a rider slidably mounted on said bars and adapted to bereceived in the recess between said toe portion and said gauge member,means for fixing said toe portion to said rider, means carried by saidrider for retaining said rider in fixed relation to said bars, a secondrider slidably mounted on said bars, means carried by said second riderfor retaining said second rider in fixed relation to said bars, andmeans carried by said rider to adjust said rst rider and the gaugemember fixed thereto so that the gauge markings on said bar and on saidgauge member can be adjusted one with the other.

2. The invention as in claim 1 wherein the projections on said 4bars andthe gauge member are provided with openings therein to receive markingtools to determine the centers of openings and the like.
